Now the mobile phone is very powerful. Coding boarding pass photos can generally be done on mobile phones. First, take the boarding pass photo with the mobile phone photo function, then open the mobile phone photo album, click the photo to be released, and then click the photo? Editor? Function, you can find the mosaic inside, select the mosaic pattern as needed, and click to encode the name, certificate, QR code, etc. On the boarding pass photo, adjust the size of the mosaic according to the occlusion information, and finally save the edited photo and publish it to the circle of friends.
The boarding pass is a certificate for passengers to fly. Many people can't wait to share their boarding passes with their friends when traveling by air. People with high awareness of prevention will also embed their names and ID numbers on boarding passes when sharing. In fact, even if the boarding pass photos are encoded and published, there will inevitably be omissions and there is a certain risk of personal information disclosure. So I suggest that you don't send such a circle of friends or try not to send it well.
